could you please publish the PayloadFormat-DECODER you're using for all ports?
thanks!
with the new version (original GPS positioned at the window) I get
17:40:21 5 4 dev id:rak811_tracker_01 payload:0371000000000000
17:39:58 4 3 dev id:rak811_tracker_01 payload:026701220403019A
17:37:50 3 2 dev id:rak811_tracker_01 payload:0188073CB5014DA200C990

Impossible to send a simple photo here. Everytime I try to upload, I have an error "your connection was lost, please wait" anyway, GPS is not functionnal and I'll to know If I am the only one. If other person are able, please share your way

We do not know at this moment whether it is caused by your improper operation or module problem, so please provide evidence of your module problem. If we confirm that there is a problem with the module, we will send you a good module for you again.
